The text, font, position, scaling, rotation, and colors of a custom label can be set. In addition, the visibility of the borders and background of the label can be toggled. Colors, borders, and background are determined by the active theme unless set explicitly.
注意: In scaling, the z-coordinate has no effect. Setting the same x- and y-coordinates retains the original font dimensions.
另请参阅 QAbstract3DGraph::addCustomItem ().
This property holds the color for the label background, if enabled.
默认为
Qt::gray
.
访问函数:
QColor | backgroundColor () const |
void | setBackgroundColor (const QColor & color ) |
通知程序信号:
void | backgroundColorChanged (const QColor & color ) |
另请参阅 backgroundEnabled .
此特性保持是否启用标签背景。
若设为
false
,
backgroundColor
() 不起作用。默认为
true
.
访问函数:
bool | isBackgroundEnabled () const |
void | setBackgroundEnabled (bool enabled ) |
通知程序信号:
void | backgroundEnabledChanged (bool enabled ) |
This property holds whether label borders are enabled.
默认为
true
.
访问函数:
bool | isBorderEnabled () const |
void | setBorderEnabled (bool enabled ) |
通知程序信号:
void | borderEnabledChanged (bool enabled ) |
This property holds whether the label will always face the camera.
默认为
false
。若设为
true
,
rotation
() has no effect.
访问函数:
bool | isFacingCamera () const |
void | setFacingCamera (bool enabled ) |
通知程序信号:
void | facingCameraChanged (bool enabled ) |
This property holds the font to be used for the label.
默认为
QFont("Arial", 20)
. Special formatting (for example, outlined) is not supported.
访问函数:
QFont | font () const |
void | setFont (const QFont & font ) |
通知程序信号:
void | fontChanged (const QFont & font ) |
This property holds the text for the label.
Rich text is not supported.
访问函数:
QString | text () const |
void | setText (const QString & text ) |
通知程序信号:
void | textChanged (const QString & text ) |
This property holds the color for the label text.
Also affects the label border, if enabled. Defaults to
Qt::white
.
访问函数:
QColor | textColor () const |
void | setTextColor (const QColor & color ) |
通知程序信号:
void | textColorChanged (const QColor & color ) |

Constructs a custom 3D label with the given text , font , position , scaling , rotation , and optional parent .
注意: Setting the same x- and y-coordinates for scaling retains the original font dimensions.
Constructs a custom 3D label with the given parent .
[虚拟]
QCustom3DLabel::
~QCustom3DLabel
()
Deletes the custom 3D label.
